In the deep sea.

Lin Qiye and Amamiya Qinghui slowly dived, and the beam of the flashlight passed through the dark sea water and landed on the reef at the bottom.

They clinged to the bottom of the sea, searching around, Lin Qiye's spiritual power was stretched to the extreme, like a radar monitoring the surrounding environment at all times, and finally, as if he sensed something, he gestured to Amamiya Qinghui.

Amamiya Qinghui nodded, followed behind Lin Qiye, and swam in a certain direction.

After the two of them wandered under the sea for a long time, the flashlight beam suddenly deepened, and the submarine reef under them had disappeared, replaced by a huge submarine crater with a radius of several hundred meters.

The outline of the crater is a circle, extending towards the bottom, standing next to the crater and looking down, the flashlight beam shining in the dark seawater, it is impossible to see the bottom of the crater.

The two looked at each other, nodded at the same time, and then jumped down to the bottom of the pothole.

In the endless darkness and seawater, the two of them don't know how long they fell, since entering this pit, the rules of physics seem to have changed mysteriously, the buoyancy of the sea water did not slow down their fall, but made them faster and faster.

In the end, neither Lin Qiye nor Amamiya Qinghui could control the speed of their diving, and they couldn't even judge how deep they had sunk.

As time passed, the two suddenly felt a whirlwind of the sky, and the whole person was ejected from the seawater, crossed an arc in the air, and fell heavily to the ground.

Amamiya Haruki frowned, wearing bulky diving equipment, slowly got up from the ground, and his eyes swept around suspiciously under the diving goggles.

The surroundings were pitch black, but from the beam of the flashlight, he could almost make out that what they were in was probably a low cave, and that the place where they had just ejected from the water was a vast deep pool about thirty meters away.

"Hoo ......"

Lin Qiye took off his mask, sniffed lightly, and after confirming that there was enough air here, he began to take off the diving equipment on his body.

A moment later, the two of them walked to the deep pool, holding a flashlight and carefully sweeping the deep pool.

"This deep pool is connected to the sea area where we came down?" Amamiya Haruki said with some confusion.

"It should be." Lin Qiye nodded slightly, "After passing through that strange undersea pit, I was thrown here directly...... But I always felt that we had sunk very deep in the pit, and this place might not be just the bottom of the sea, but more like a separate space. ”

"My master said the same." Amamiya Haruki sighed, "However, he didn't figure out what this ruin was. ”

"That's our mission." Lin Qiye looked up at the road on the other side of the cave and said, "Anyway, let's go forward first." ”

The two of them walked slowly forward along the narrow cave, and Amamiya Haruki hung the [Rain Collapse] on his waist, put his palm on the hilt of the knife, and was always vigilant around.

Although it is not possible to use the Kazu Knife here, if you only draw the knife and use the sword technique, instead of using the ability of the Katsu Knife, the knife will not be sucked away by the mysterious power, although this is just a rumor that Amamiya Haruki heard from his master, but he has no intention of trying to die.

After all, there is only one [Rain Avalanche], and once this knife is sucked into the depths of the ruins, it will not be so easy to get it back.

Fortunately, along the way, I didn't encounter any enemies.

"We're coming to an end."

The two walked along the cave for a long time, and Lin Qiye's spiritual power sensed the changes ahead and opened his mouth to remind.

Amamiya Qinghui nodded, and was about to say something, Lin Qiye's face suddenly changed, and he suddenly stretched out his hand to stop Amamiya Qinghui who was advancing!

"Wait! Don't go any further. ”

Amamiya Haruki's feet lifted into the air, slowly put them back again, and asked suspiciously, "What's wrong?" ”

Lin Qiye didn't answer, but walked to the side of the cave walkway, slowly squatted down, and shone the light of the flashlight on the corner of the wall, where there was a thumb-sized miniature laser emitting device hidden in the groove, and on the opposite side of the wall, there was also one such device.

These two launchers were small in size and black, and they were difficult to detect in the pitch-black cave, if it weren't for Lin Qiye's spiritual power perception, he would definitely ignore their existence.

Amamiya Qinghui squatted down and asked curiously, "What is this?" ”

"Infrared siren." Lin Qiye knew this kind of equipment, frowned and explained, "Once someone passes by here, an alarm signal will be sent out and transmitted to the person who set this thing." ”

"Is this artificially placed?"

"Of course, and it won't be left out for long." Lin Qiye said firmly.

He looked up at the end of the cave not far away, paused, and slowly spoke, "It seems that someone came to the ruins before me, and they also have professional anti-tracking knowledge and ability......"

"Is that the mysterious guy who bought the diving equipment?"

"Nine times out of ten, it's him, and he's quite alert, and while we're noticing his abnormality, he's probably already starting to suspect us, and this alarm should be prepared to guard against us."

Amamiya Haruki's brows furrowed slightly, feeling that something was wrong.

In such a dangerous ruin, there is also a mysterious person who seems to be friend or foe, and the other party also has a strong combat capability...... This is definitely bad news for him who can't use the Disaster Knife.

If he hadn't brought Lin Qiye this time, he was afraid that he would have been completely exposed by now.

"So what do we do now?"

"Tear it down, you can't startle the snake." Lin Qiye said calmly, "I learned this knowledge in the training camp, give me two minutes." ”

Next, Amamiya Qinghui watched Lin Qiye dismantle this infrared alarm device with a subtle means, and the latter slowly stood up, looked at the end of the cave not far away, and said in thought:

"He wouldn't have been too alert if we hadn't set off the alarm, and now we're both in the dark...... It's up to whoever exposes themselves first. ”

After dismissing the alarm, the two of them continued on their way, straight through the narrow passageway, their feet on the scorched and wasteland-covered earth, and the environment around them completely changed.

In the hazy sky, a hazy pale blue shimmer distorted like an aurora and poured down from the top of the clouds, and one crumbling tall building after another was buried among the wasteland, some half submerged, others upside down, like barbs to the ground.

Tarmac gravel, fragmented glass shards, broken tables and chairs, dry deep-sea corals...... The dense bits and pieces seemed to have completely escaped gravity, hovering in the air in an unbelievable way.

It's like a chaotic garbage can, full of fragments of the city and the corpses of the deep sea, but strangely blended together.

It seems to have been washed here by some mysterious force, and it should have sunk at the bottom of the deep sea, the remains of human society.
